Abstract

A circuit arrangement for a reversible image build-up of a surface matrix of a printing form for a printing machine, wherein the surface matrix has regions which are activatable and de-activatable by repeated triggering, includes a respective electrical circuit operatively associated with every region of the surface matrix activatable and de-activatable by the repeated triggering, at least one threshold value switch connected in each of the electrical circuits and having a switching state variable by the triggering for respectively activating and de-activating the region operatively associated therewith.
